Question

20men working 8hours a day took 18days to complete a work . How long will 24 men working 5 hours a day take to complete the some work

Answer 1

Step-by-step explanation:

20 men work 8 hours a day for 18 days.

that are

20×8×18 = 2880 work hours to complete that work.

if 24 men work 5 hours a day, that are

24×5 = 120 work hours per day.

we still need to do the total 2880 work hours.

so, they will need

2880 / 120 = 24 days to complete the work.
